Evaluate y = [X + 1] at x = 3.001?

PSYCHO15rus [73]

Answer: 4

Step-by-step explanation:

Given

$y=[x+1]$

where, $[ ]=$ Greatest integer function

Put $x=3.001$

$\Rightarrow y=[3.001+1]=[4.001]\\\Rightarrow y=[4+0.001]=4$

Thus, the value of y is 4

How do you solve a for percent

kirill115 [55]

Answer:

If you want it as the previous number without being a percent you just have to multiply the percent by 100 to get the previous amount. For example:-

to convert 30% to a number put in a fraction form and multiply it by 100

$\frac{30}{100}*100=\frac{3000}{100}=30$ You can find the previous value of any percent by doing this.

Can anybody help me figure out the area of simple composite figure?

zvonat [6]

Given:

The length of the rectangle = 16 ft

The width of the rectangle = 12 ft

The diameter of the semicircle = 12 ft

To find the area of the given figure.

Formula

$A=A_{1} +A_{2}$

where,

$A$ be the area of the given figure

$A_{1}$ be the area of the rectangle

$A_{2}$ be the area of the semicircle.

The area of the rectangle = $lb$ where, l be the length and b be the width
Area of the semicircle = $\frac{1}{2} \pi r^{2}$ , r be the radius of the semicircle.

Now,

The radius of the semicircle r = 6 ft

Putting, r=6, l=16 and b= 12 we get,

$A_{1} = (16)(12)$ sq ft

or, $A_{1} = 192$ sq ft

$A_{2} = \frac{1}{2} (3.14)(6^{2} )$ sq ft

or, $A_{2}=56.52$ sq ft

So,

$A = 56.52+192$ sq ft

$A$ = 248.52 sq ft

Rounding off to the nearest tenth, we get;

A=248.5 sq ft.

Hence,

The area of the composite figure is 248.5 sq ft.

Select the correct answer from each drop-down menu.

Lilit [14]

Answer:

The probability of the spinner landing on an even number or a multiple of 3 is 0.6667 .

The probability of the spinner landing on an odd number or a number between 4 and 15 (both numbers excluded) is 0.7778 .

Step-by-step explanation:

Be the events

A = even number

B = Multiple of 3

C = Odd Number

D = Number between 4 and 15, both numbers excluded

The sets are as follows:

A = {2,4,6,8,10,12,14,16,18}

B = {3,6,9,12,15,18}

C = {1,3,5,7,9,11,13,15,17}

D = {5,6,7,8,9,10,11,12,13,14}

To calculate the probability that the roulette lands in an even number or in a multiple of 3, we make the union of A and B:

A U B = {2,3,4,6,8,9,10,12,14,15,16,18} = 12 numbers of 18

P (A U B) = 12/18 = 2/3 = 0.6667

To calculate the probability that roulette lands on an odd number or a number between 4 and 15 (both numbers excluded), we make the union of C and D:

C U D = {1,3,5,6,7,8,9,10,11,12,13,14,15,17} = 14 numbers of 18

P (C U D) = 14/18 = 7/9 = 0.7778

The first answer is 0.6667

The second answer is 0.7778

Hope this helps!
